7) Denial of service (CVE-ID: CVE-2018-4460)

The vulnerability allows a local attacker to cause DoS condition on the target system.

The weakness exists due to an error in the Kernel component. A local attacker can conduct DoS attack and cause the device to crash.


8) Information disclosure (CVE-ID: CVE-2018-4431)

The vulnerability allows a local attacker to obtain potentially sensitive information on the target system.

The weakness exists due to a boundary error in the Kernel component. A local attacker can trigger memory corruption and read kernel memory.


9) Privilege escalation (CVE-ID: CVE-2018-4435)

The vulnerability allows a local attacker to gain elevated privileges on the target system.

The weakness exists due to a logic issue in the Kernel component. A local attacker can run a specially crafted application and gain elevated privileges.


10) Spoofing attack (CVE-ID: CVE-2018-4429)

The vulnerability allows a remote attacker to conduct spoofing attack on the target system.

The weakness exists due to insufficient validation of user-supplied input in the LinkPresentation component. A remote attacker can send a specially crafted mail message and spoof UI.


11) Spoofing attack (CVE-ID: CVE-2018-4439)

The vulnerability allows a remote attacker to conduct spoofing attack on the target system.
